Application filed September 2, 1905. $erial No. 276,868-

To a /Z} whom it may concern:

Be it known that I, HUME PURDIE, dental surgeon, a subject of the KingofGreat Britain and Ireland, and a resident of 9 Gilmore Place,Edmburgh, Scotland, have invented 'struct an apparatus which will be putinto an active or operative state on inserting a coin therein in amanner similar to a penny-inthe-slot machine.

The machine is so constructed thatwhen liberated by inserting a coin thegolf-ball used in combination therewith will on being struck registerand record on a dial the distance the ball would have traveled onreceiving the stroke. The machine is specially adapted for testing thedriving and putting abilities of the player.

Referring to the drawings which form. a part of this specification,Figure 1 is a sectional elevationlooking in at the front of the improvedmachine. Fig. 2 is a sectional elevation looking in at the side of themachine. Fig. 3 is'a front elevation of part of a machine, showing adial for indicating the distance struck. Fig. 4 is a detached view ofthe turning-back mechanism. Fi 5 is an enlarged sectional elevationof'the bucket or coin-holding device.

According to this invention the improved machine is preferably inclosedin a cast-iron casing 1, covered on the top by a removable hood 2, whichis provided with a glass face 3 for a dial 4, the lower part of thecasing being provided with doors 5. The casing 1 is bolted 'or otherwisesecured to a horizontal casing 6, which hes below the level of theground and extends a suitable distance away from the casing 1. The endof the casing 6 is enlarged or made deeper, as at 7, to allow of thefree rotation of the golf-balls 8. These latter may consist ofcompressed felt, guttapercha, or other suitable material and are mountedon two or more arms 9, radiating from a boss 10, fixed on a shaft 11,free to turn in the bearings 12. The balls 8 are slightly raised abovethe level of the ground, and the top of the casing 7 is recessed, as at13, to enable a rubber pad 14 to be secured thereon. The pad 14 ispreferably convex or cone shaped and serves to prevent the bottom orsole of a golf-club from. coming into contact with any of the ironwork.

The shaft 11 is connected by means of a spring-coupling 15 to a shaft16,eXtending along the casing6 and supported by bearings 17 therein.Fixed on the shaft 16 is a pinion 18, connected by a chain 19 to thechainwheel 20, which drives a chainof wheels for moving the pointer 22over the dial 4, which ispreferably divided into'feet and yards. Fixedon the'wheel 21 or to the axle of same is a weight 23, and the lowerpinion 21 is formed with a blank space or has a number of teeth missing,as shown in Fig. 4. Working in combination with the aforesaid weight isa lever 24, from which hangs a rod 25, the lower end of which is crankedto engage with the hooked rojectlon 25, which is connect ed to a bloc 25pivoted in the bucket 26. The latter is mounted on one end of a pivoted.lever 27, the other end of which is connected by the rod 28 to aclutch-lever 29 which gears With'and controls the clutch 30, fixed onthe'shaft 16. Situated below the bucket 26 is a chute 31 for directingthe coins into the compartment 32, which is accessible by means of thedoors 5. g

The action is as follows: A coin is first inserted through an opening inthe easing into the bucket 26, and the weight of the coin causes thelever 27 to turn on its pivot and to lift the clutch-lever 29 out ofconnection with the clutch 30. The shaft 16 is now free to revolve andthe balls 8 are in a playable condition. When the pointer indicates thenumber of yards marked on the dial, the blank space on the wheel 21comes opposite tov the wheel 21, as shown in Fig. 4. The wheel 21 isconsequently released and the weight 23 operates same to return thepointer to zero. In traveling back the weight comes into contact withthe pivoted lever 24 and turns the latter, so that the rod 25 is raised,thereby lifting the block 25 and allowing the coin or token to fallthrough the bucket 26 and into the compartment 32. The weighted lever-27 now returns to its original position, and the clutch-lever 29 islowered into gear with the clutch 30, and the shaft 16 is locked and theballs rendered un layable.

Having now descri ed my invention, what I claim as new, and desire-tosecure by Letters Patent, is v I 1. The combination, witha revolublesup- IIO porting-shaft, and a captive golf-ball connected to the saidshaft; of an operatingshaft, a spring-coupling between the two saidshafts, and distance-indicating mechanism driven by the saidoperating-shaft.

2. The combination, wlth a revoluble supporting-shaft, and a captivegolf-ball connected to the said shaft; of an operatingshaft, aspring-coupling between the said shafts, distance-indicating mechanismdriven by the said operating-shaft, a locking-clutch controlling thesaid operating-shaft, and means for operating the said clutch at will torelease the said operating-shaft.

3. The combination, with a casing having an opening in its upper side,of a revoluble shaft arranged inside the said casing and provided withan arm which projects through its said opening, a dummy golf-ballcarried by the said arm, an operating-shaft also arranged inside thesaid casing, a sprmg-coupling between the two said shafts, anddistance-indicating mechanism driven by the said operating-shaft.

4. The combination, with a casing having an opening in its upper side,of a revoluble shaft arranged inside the said casing and provided withan arm which projects through its said opening, a dummy golf-ballcarried by the said arm, an operating-shaft also arranged inside thesaid casing, a spring-coupling between the two said shafts, alockingolutch controlling the said operating-shaft, means for operatingthe said clutch at will and thereby releasing the said operating-shaft,and distance-indicating mechanism driven by the said operating-shaft.

In testimony whereof I afiix my signature in presence of two witnesses.

HUME PURDIE.
